Do you see yonder cloud that’s almost in shape of a camel?
There's a picture of a Melissandre miniature painted eerie bluish instead of red under the instructions of GRRM. Emilia Clarke once slipped when Stannis was strangling Melissandre, she looked like she came back from dead "because...oh wait, we're not supposed to talk about this yet". Finally Oliver Ford Davis (Maester Cressen) let it slip in an interview Melissandre is 400 years old. I wish I was allowed to post links to prove it to you. So what do you think it's the deal with Melissandre?
